ければならない場合がある。 When a photoelectric conversion element is used, for example, as a light emitter or a light receiver, it is usually housed and supported in a cylindrical container.
Light is emitted or received from one end of the container, and a lead wire for electrical connection is connected from the other end.
In this case, the optical axis of the photoelectric conversion element housed inside must be supported so as to coincide with the cylindrical axis of the container. There are two types of photoelectric conversion elements: those that are approximately cylindrical, and those that are approximately spherical and have two lead wires installed in a direction perpendicular to the optical axis of the photoelectric conversion element.
The former case is relatively easy to support, but the latter poses many difficult problems. However, in general, light emitting elements with a small light emitting area are often of the latter type, and there are cases where the latter type has to be used due to design requirements, such as when a point light source is required.

ク等を生じることがない。 In order to support the photoelectric conversion element with the support structure of this embodiment, the photoelectric conversion element 8 is placed inside the first auxiliary member 2 with the lead wires 9 protruding in the vertical direction, as shown in FIG. After inserting the second auxiliary member 6 into the first auxiliary member 2,
The photoelectric conversion element 8 is held between the first and second auxiliary members. The outer diameter of the second auxiliary member 6 is the same as that of the first auxiliary member 2.
Since it is slightly larger than the inner diameter of the inner diameter, it will fit tightly if inserted with pressure. Next, the lead wire 9 is bent at a substantially right angle and inserted into the slot 5, with the tip end projecting outward. The first auxiliary member 2 may be fitted into the cylindrical container 1 in this state. The photoelectric conversion element 8 is held between the first and second auxiliary members 2 and 6, and the lead wire 9 is held within the slot 5, so that it is stably held in the cylindrical container 1. The optical axis coincides with the cylinder axis. In this case, it is extremely desirable that the portion of the first auxiliary member 2 where the through hole 4 contacts the photoelectric conversion element 8 be formed in a shape that fits well with the tip of the photoelectric conversion element 8;
It is desirable that the sliding portion 5 of the auxiliary member 2 be approximately equal to the outer diameter of the lead wire 9 of the photoelectric conversion element 8. With the above configuration, the photoelectric conversion element 8 can be easily and stably accommodated and supported in the cylindrical container 1. Since the optical axis coincides with the cylinder axis, light can be transmitted and received stably over a long period of time. Further, in this embodiment, the auxiliary members 2 and 6 and the photoelectric conversion element 8 can be integrated and treated as one cylindrical photoelectric conversion element, and parts can be easily replaced. Further, the external force applied to the tip of the lead wire will not be applied to the base of the photoelectric conversion element 8 and cause cracks or the like.
